A recent wall of ours in a similar mid grey. You'll get the actual Grey Textile board in your hand at the visit.
The look
Like good suit cloth
Grey Textile has the fine tailored weave of good suit cloth. It's a mid grey with structure and softness at the same time. Under LED light the weave shimmers a little, and in daylight it reads calm and precise.
It's a smart middle ground between a plain matt board and a bold stone. Up close you notice the texture, and across the room you just feel how settled it is.
Black Oak thin slat sharpens it. Sinner Oak keeps it softly tonal, and Walnut adds a bit of warmth.
